Engine Mangement System for 351 Windsor

Can anybody point me in the right direction toward what kind of computer, MAF meter, and injectors I should use for my 351w roller with c/6 transmission. This is a 4x4 F-250 3.55 gears which will be used for actual truck duties such as hauling and towing.

I am using long tube headers, GT40P heads, Comp 35-349-8 roller camshaft, GT-40 lower and upper intake, with 75mm single throttle body.

I am lost as to which injectors and computer I should use to make use of these bolt-ons. I am leaning towards a mustang computer, but then I feel that the "tune" would be geared toward a small lightweight car. Are there other options that EEC-IV?

The main question these days is why use a 30+ year old ECU of questionable quality (the capacitors in the original ECU's are failing a lot at this point) that locks you into an old ecosystem that costs a lot of money to have someone tune for you when you can instead get a modern plug and play standalone ECU that uses your stock harness and mounts in the stock ECU location and has all of the latest features, gives you complete control of all aspects of tuning, has tons of built in features the stock ECU's couldn't even dream of, and it's got a self tuning feature and great support so you can tune it yourself without paying anybody else to do it for you? I'm referring to this: https://www.stinger-performance.com/...ine-management

Well, cost is a major criterion but I am willing to shell out if it's worthwhile. I like the stinger, but notice it is batch fire....MAF is something I want in order to save fuel and its adaptability. Is there a similar product with MAF?

The one above can run MAF, that's not a problem. Nobody does so since speed density works so well with modern tunable ECU's (my Wife's brand new car twin turbo and is speed density for example). Regardless, it can use a MAF if you want to spend the extra money for the sensor/plumbing and such. The whole "MAF is better than SD" is only with stock ECU's. Once you can tune all parameters, the benefits of MAF goes away as an ECU with no tuning limitations is as adaptable as it can get. An example of the adaptability is the PiMPx can run basically ANY mid 80's to mid 90's Ford engine (4 cyl, 6 cyl, small block V8, big block V8, inline 6, etc.) whether they are n/a, nitrous, turbo, supercharged, stock, highly modified, big cam, any injector size, etc. Can also do things like be flex fuel to allow you to run e85 if you want, etc.

If you want to add 6 injector wires to your harness and run sequential (with or without MAF) then this version is the sequential ECU: https://www.stinger-performance.com/...ine-management The reason you have to add 6 wires is your current harness only has 2 injector wires going to the ECU so in order to control each injector individually (not in batches), it needs a wire for each injector going to the ECU.
